Settings

Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).
Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.
Adjust the audio volume by selecting a number of decibels. For example, -10 dB decreases the volume by 10 decibels.

wmv

WMV (Windows Media Video) is a family of video codecs and associated file format developed by Microsoft, first introduced in 1999 as part of the Windows Media framework. The format encompasses several codec generations, from the original WMV 7 through WMV 9 (also standardized as VC-1 by SMPTE under the 421M specification). WMV files are typically contained within the ASF (Advanced Systems Format) wrapper and use the .wmv extension to indicate video content. WMV 9/VC-1 achieved compression efficiency comparable to early H.264 implementations, delivering good visual quality at moderate bit rates and earning adoption for HD DVD and Blu-ray disc content as an approved codec. The format was deeply integrated into the Windows operating system, Windows Media Player, and server-side streaming infrastructure, making it a natural choice for enterprise media delivery, corporate training videos, and Windows-centric web content throughout the 2000s. WMV supports features including interlaced video, multiple bit rate encoding for adaptive streaming, and digital rights management through Windows Media DRM. The Silverlight platform also used WMV as its primary video format for rich internet applications and streaming services. While the industry has largely moved to H.264 and HEVC for most applications, WMV remains present in legacy enterprise content management systems, archived media libraries, and workflows tied to the Windows Media ecosystem.

flac

FLAC (Free Lossless Audio Codec) delivers mathematically perfect audio reproduction at roughly half the size of an uncompressed WAV file. Maintained by the Xiph.Org Foundation and released in 2001, it quickly became the de facto open standard for lossless music archival. The encoder applies linear prediction to model each audio block, then codes the residual through Rice partitioning — exploiting the statistical distribution of prediction errors for strong compression without discarding data. Bit depths up to 32 and sample rates up to 655 kHz are supported, exceeding the requirements of high-resolution recordings. Hardware support is extensive: smartphones, car stereos, Blu-ray players, and virtually every desktop media application decode FLAC natively. Streaming services such as Tidal and Amazon Music use FLAC for lossless tiers, underscoring industry trust in the codec. Three standout benefits make FLAC compelling. First, complete bit-for-bit restoration of the original signal upon decoding. Second, embedded metadata via Vorbis comments and album art keeps libraries organized without sidecar files. Third, open-source licensing means no patents or royalties, removing legal friction for developers and hardware vendors.

Frequently Asked Questions

Why convert WMV to FLAC?

WMV, Microsoft's Windows Media Video format, can be hard to play across platforms. Switching to FLAC gives you broad support across modern players.

How do I open a FLAC file?

Open FLAC with VLC, foobar2000, Winamp, or dedicated hi-fi audio players. Most handle the format without any extra plugins or codecs.

Does converting WMV to FLAC keep only the audio?

Yes — when you convert a video format to FLAC, the converter extracts the audio track and discards the video stream entirely.

Does the conversion work on mobile?

It does. Convertio.tools works in any modern mobile browser — upload your WMV, convert to FLAC, and download directly on your phone.

Can I adjust the output bitrate?

Yes — set the desired bitrate before converting. Lower bitrates produce smaller files, while higher bitrates preserve more audio detail.
